Paragraph

Welcome to my genetics page. Genetics is a very important thing in life.Augustinian monk Gregor Mendel discovered genetics by studying pea plant over time. It teaches about heredity and genes.
Some rules about genetics are:
each inherited trait has two alternative form
Genes come in pairs
Mendel wrote 3 laws of heredity:
1) The Law of Segregation: Each inherited trait is defined by a gene pair. Parental
genes are randomly separated to the sex cells so that sex cells contain only one
gene of the pair. Offspring therefore inherit one genetic allele from each parent when
sex cells unite in fertilization.
2) The Law of Independent Assortment: Genes for different traits are sorted
separately from one another so that the inheritance of one trait is not dependent on
the inheritance of another.
3) The Law of Dominance: An organism with alternate forms of a gene will express
the form that is dominant

Guppy

1. Female guppys are the most attracted to the most brightly colored males, giving those males a more likely opportunity to pass their genes on to the next generation.
2. The guppy I find most interesting is the Poecilia reticulata. Its origin is Brazil, and its average size is 1.4 inches. Its color is mostly black, with yellow orange and green spots and fins.
3. The predator I found to be most interesting was the Dormitator maculatus. It is usually 27.5 inches in size, and its origin is Southern North america, the Bahamas, and Latin america.
4. Guppy habitats near mid sized dams can help keep predators out, by keeping them from moving upstream.
5. John Endler is a Ethologist and evolutionary biologist. He studies adaptation and vertebrates, and does a lot of work on guppies. He got this information from the University of Edinburgh.
6. Pool 1: Brightly multi-colored with large spots.
Pool 2: Medium coloration on body and tail with medium sized spots.
Pool 3: Drab coloration, very small spots, and concentrated near the tail.
7. Because certain guppies genes from that area, havnt reached other areas yet. So the brightly colored genes may not have reached the drab colored pool.
Simulation:
Trial 1: 37% Brightest, 48% bright, 9% drab, 6% drabbest.
Trial 2: 3% brightest, 35% bright, 63% drab, 0% drabbest.
Trial 3: 11%, brghtest, 3% bright, 8% drab, 78% drabbest.
Trial 4: 63% brightest, 31% bright, 6% drab, 0% drabbest.
Trial 5: 0% brightest, 0% bright, 8% drab, 92% drabbest.
8. Bright guppys are more likely to be eaten by predators, so their genes wont be passed on. This means predators affect the brightness of the guppies coloration.
9. Yes, I accept it. Thats why theres not a perfect mix among pools.
10. It means that they have to try to find mates, while avoiding predators at the same time. It is already tough enough to mate, but with predators chasing them around, they are definitely in a crossfire.
11. Explained in Number 7/9.
12. The drab guppys population would rise, because the few predators would have trouble finding them anyway.
13. The brightly colored guppies population would fall, because of all the predators and their bright obviously seen colors.

Biodiversity

it benefits humans in a lot of ways including genes, natural products and food sources. It affects more areas because when one area gets destroyed it might affect another by less food sources. it helps the life of people because with more diverse types of animals more things can be made and more food sources can be made. Without cows there wouldn't be any milk and milk is one very important food source. With more animals there can be a lot more food for humans to survive.

Chernobyl Questions

What was the disaster?
Where did all the animals come from?
Who caused it to blow up?
How coul the animals move in?
Were they affected by it?

Chemical Dispersants

Do you think that there is another better solution for the oil spill ? Why did BP keep it a secret? How can the chemical dispersants hurt animals?
